Unscheduled reboot

I've unchecked the reboot option on the display I'm using, but the display keeps rebooting at the exact same time as it used to. Do I have to do something more than uncheck the reboot box in display settings?

The only thing you need to make sure of is that the device has come online and communicated with Rise VIsion successfully since making that change. If the device is still offline in Rise Vision, it will not see that update, and therefore will not be updated to reflect that time change.
